To keep things simple, I won’t go into the details of each syntax of a Prometheus metrics and how they are different. Because Prometheus uses a standard data-model with a key-value based metrics that might not match with the third-party system this is why you use exporters to convert them. It is important to know that metrics that you get from a third-party system are different from the Prometheus metrics.

An Exporter is a piece of software that gets existing metrics from a third-party system and export them to the metric format that the Prometheus server can understand.Ī sample metric from a Prometheus server could be the current usage of free memory or file-system free via a Node Exporter in the Prometheus server.
But Prometheus is not only about application monitoring, you can use something called Exporters to monitor third-party systems (Such as a Linux Server, MySQL daemon etc). Prometheus provides client-libraries in a number of languages that you can use to provide health-status of your application. In other words, you ask the Prometheus server via PromQL to show us the status of a particular target at a given time. You get the metrics details by querying from the Prometheus’s time-series database where the Prometheus stores metrics and you use a query language called PromQL in the Prometheus server to query metrics about the targets. You define the targets to be scraped and the time-interval for scraping metrics in the prometheus.yml configuration file.
The Prometheus server scrapes targets at an interval that you define to collect metrics from specific targets and store them in a time-series database. So Prometheus server collects metrics from targets (over HTTP), stores them locally or remotely and displays them back in the Prometheus server. It could be a single server or a targets for probing of endpoints over HTTP, HTTPS, DNS, TCP and ICMP (*Black-Box Exporter), or it could be a simple HTTP endpoint that an application exposes through which the Prometheus server gets the application's health status from.Įach unit of a target such as current CPU status, memory usage (in case of a Linux server Prometheus Target) or any other specific unit that you would like to monitor is called a metric. As said earlier, "Targets" can also refer to an array of things. So the Prometheus server monitors Targets. In Prometheus terms, we call the main monitoring service the Prometheus Server and the things that Prometheus monitors are called Targets. That thing could be anything: it could be a an entire Linux server, a stand-alone Apache server, a single process, a database service or some other system unit that you want to monitor. As a monitoring service, Prometheus servers monitor a particular thing. Prometheus has a main central component called Prometheus Server. Let’s see first that what are the main mandatory components in Prometheus from ground-up.

You will see how to spin up a minimal Prometheus server with a Node Exporter and a Grafana components in Docker containers to monitor a stand-alone Linux Ubuntu 16.04 server. Prometheus is fully Docker compatible, and a number of Prometheus components within Prometheus itself are available on the Docker Hub.

You download and run Prometheus with its components it's that simple. This means you have a single binary executables.
Some of its components are written in Ruby but most of the components are written in Go. Prometheus is an open-source and one of the popular CNCF projects written in Golang. What Exactly Is Prometheus and How It Is Different? In this post, we will take a look at the Prometheus monitoring, a popular free & open-source project for monitoring dozens of services. With monitoring, there are a number tools out there such Amazon CloudWatch, Nagios, New Relic, Prometheus and others. You also want to get some type of notification if CPU or memory usage goes up for a certain period of time or a service of your application stops responding so you can perform appropriate actions against those failures or exceptions. You want to continuously monitor your applications and servers for application exceptions, server CPU & memory usage, or storage spikes. Monitoring applications & application servers is an important part of the today’s DevOps culture & process.
